On his first couple of high altitude flights, Kit said his plane would snap into a spin when the motors burned out while approaching his peak altitude.

He then shut down the engines and glided to the peak altitude.

The peak altitude is 1,600 metres above sea level, the lowest part is 1,300 metres above sea level.

It would incorporate a rocket engine for acceleration to achieve a planned peak altitude of almost 300,000 feet.

The peak altitude is reach with Mount Dimlang (formerly Vogel) at 2,042 m (6,699 ft.).

The highest mountain is Mill-Dish Mountain(磨盘山) with its peak altitude 1366.6 meters.

In 1951, Douglas test pilot Bill Bridgeman flew the skyrocket to a top speed of Mach 1.88 (1,180 mph) and a peak altitude of 74,494 feet.

It was also found that the percentage of oxygen at the peak altitude was about the same as that at sea level.

He flew the aircraft 14 times during the following two years, reaching a maximum speed of 3,712 mph (Mach 5.48) and a peak altitude of 214,100 feet on separate flights.

It can reach a peak altitude of 150 m (500 ft) in top-attack mode and 60 m in direct-fire mode.
